I recently bought a nice PK2 burner off ebay, and the seller mentioned
it has a "programmer extension" not included. Not sure what that
means.

Here is the snippet from the ebay page:

"You are bidding on one pic kit 2 programmer for be used with
Microchip PICKIT2 to work on pic microcontrollers just using your own
circuit and the ICD2 interface or the available programmer extension
(not included)."

I know that guy. So far _MY_ Pickit2 from him doesn't work. Just a warning.

Pure Microchip based solution is a bit too complicated.
Quote from the answer of the current PICkit 2 developer Walter:
"There is the AC162049 Universal Programming Adapater that can be used with
PICkit 2 with the AC164110 RJ-11 to ICSP adapter. One other item of importance
is that the resistor R1 must be removed from the Universal Programming
Adapter for
PICkit 2 use, as the PICkit 2 VPP pin can't support the current to
drive the LED."

That was one point which prevented me from getting one for some time
(actually I did not need it since I have my own USB programmer).
But I chose to get it from AUgroups since its price and shipment were
reasonable (10$).

They may mean the PicKit2 demo programming board. ( http://www.microchipdirect.com/productsearch.aspx?Keywords=DV164120 ).
It's a great board to carry with the PicKit2 and a laptop for trying out
programs and/or playing. The 8 pin chips can use the leds simply by
adding jumpers to the inline header, and the header looks like it could
drive a character LCD. The PicKit2 Starter kit includes the demo
programming board - I gave one to an electronics student as a Christmas
gift - it comes with tutorials and demo software that is a nice
introduction to Pics.

With the RJ12 connector designed on our CB0703 (PICkit2), a "RJ12 6-pin reverse cable (part #CBL-RJ12-RVS)" can be used to connect target board/programmers designed for ICD2. Please also see "question 6" on this FAQ (Rev.B) link:

www.auelectronics.selfip.com/QandAForCB0703_RevB.pdf

Both "RJ12 Cable to Board for programming (part # CBL-RJ12-Program)" and "RJ12 6 pin Single Ended Cable (part #CBL-RJ12-SGE)" can be soldered to board directly. More info is available here:

www.auelectronics.selfip.com/System-PICkit2.htm

By the way, the promotion price for BB0703 (with lifetime warranty) will be ended after Dec-31-2007.

Several months ago, I purchased a PICKIT 2 to learn about pics. I hooked it
up when I got it, tested it and havn't used it until today. When I tried to
start it, I booted pickit2 microcontroller programmer, clicked on device
family, 14 bit core, power on and got a notice that the device was NOT
PRESENT. I reloaded the software and read the chapter in the manual, tried
again and it still doesn't work.

The Pickit 2 module has a black button and the circuit board that came with it has a 16F690 chip and 4 leds across the bottom. It's name is " Low Pin Count Demo". I havn't tried to program it yet; but, it's attached to my computer with the "busy" light blinking since I got it.

This could be a know issue, better call Microchip and find if you can have a replacement unit with red button.

The ones with black button have a small opportunity either lost the whole os or the USB power configuration bit got changed. The newest firmware fixed these issues.

Try push the button before power up and unit and see if you can enter the bootloader mode. If the computer still cannot find it, better have it replaced. It has a high possibility the USB power configuration bit got lost.

For this kind of issue, If you have another PICkit2 or ICD2, a ICSP PIC18F2550 re-program will fix it.

The busy light blinking means it's in bootload mode. Have you tried
loading new firmware into the PICkit?
